Quran 18:15. Who is the worst of the Zalimun?

Al-Kahf 18:15

“These, our people, have taken besides Him deities. Why do they not bring for [worship of] them a clear authority? And who is more unjust than one who invents about Allah a lie?”

1. Worship requires Allah’s authority

2. Who is more Zaleem of all?
   He who invents a lie against Allah.
   He who says, thinks something about Allah Subhanahu Wa Ta’ala which He didn’t reveal about Himself.
